SPINNING-FRAME.

Specification of Letters Patent.

Patented Dec. 26, 1911.

Application filed April 18, 1908. Serial N 0. 427,806.

To all whom it may concern:

Be it known that I, EPPA H. RYoN, a citizen of the United States,residing at IVorcester, in the county of WVorcester and State ofMassachusetts, have inventedcertain new and useful Improvements inSpinning-Frames, of which the following is a specification.

My invention relates to a spinning frame, or a frame for winding yarn oncops or bobbins, and more particularly to the traverse up and downmotion of the ring rail, or the guides for the yarn.

The object of my invention is to provide an improved mechanism forcommunicating a traverse up and down movement to the ring rail or theyarn guides, by means of which said rail or guides may be caused to havea movement for a comparatively short distance, when the winding of theyarn is started near the butt or lower end of the cop or bobbin, andthen the movement gradually increased as the winding of the yarnproceeds toward the outer end or tip of the cop or bobbin, and until theeX- treme length of the traverse up and down movement is reached.

In the ordinary construction of machines for winding yarn on cops orbobbins, the yarn has been wound with a uniform up and down traversemotion, causing it to be laid on the cop or bobbin with about the sameinclination at the lower end or butt of the cop or bobbin, as at theupper end or tip of the cop or bobbin. By means of my improvements, thecop or bobbin may be built up with a sharp or steep inclination or slantat the lower end or butt, thus putting more yarn on the bobbin at thebutt end, and at the same time the short traverse up and down movementof the ring rail or yarn guides at the butt end of the cop or bobbin,allows the yarn to be more readily unwound in the shuttle, when the buttend of the bobbin is reached.

My invention consists in certain novel features of construction of myimprovements as will be hereinafter fully described.

I have only shown in the drawing, a detached part of a spinning framefor winding bobbins, with my improvements applied thereto, sutficient toenable those skilled in the art to understond the construction andoperation thereof.

Referring to "the drawing :Figure 1 is an elevation of a detachedportion of one end of a spinning frame, with my improvements combinedtherewith, looking in the direction of arrow at, Fig. 2. Fig. 2 is asection, on line 2, 2, Fig. 1, looking in the direction of arrow 5, samefigure.

In the accompanying drawing, 1' is a portion of the end frame of aspinning machine, 2 is the spindle rail on which are mounted therotatable sleeve whirl spindles 3, 4: is the vertically reciprocatingring rail, provided with rings or yarn guides 55, one for each spindle,6 is one of a series of lifter rods, connected at its upper end with thering rail 4, and having its bearing on the girder 1 of the main frame 1,and connected at its lower end with the outer end of the rocker arm 7,fast on the rock shaft 8, mounted in a suitable bearing on the hanger 9.On the extension 7 on the rocker arm 7 is a counterbalance weight 10.Also fast. on the rock shaft 8 is the lower end of an arm or lever 11.To the lever 11 is pivotally connected the end of a rod or connector 12,leading to a second lever and rocker arm, not shown. To the upper end ofthe arm or lever 11 is pivotally connected one end of a rod or connector13. The other end of said rod or connector 13 is connected with a pin14, which is adjustably secured in an elongated slot 15 in the upper endof thecam lever 15. The lower hub end 15 of the cam lever 15 is looselymounted on a stud 16 in a stand 17 secured to the frame 1.

I will now describe my improvements in mechanlsm for communlcating atraverse up and down movement to the ring rail 4- 18 is a rotary shaft,operated from some Fig. 2. The cam lever 22 has a hub 22 fast on a rockshaft 23. To the cam lever 22 is attached one end of a spring 22, theother end of which spring is attached to the frame 1. Said spring 22acts to hold the roll 20 in engagement with the cam 19.

On the inner end of the rock shaft 23, which is suitably mounted in abearing 24 in the lower end of a stand 25, see Fig. 2, is looselymounted a cam 26. On the outer side of the cam 26 is fast a gear 27. Asecond gear 28 is fast on the rock shaft 23. The gear 28 has one toothless than the gear 27. A ratchet wheel 29 is loose on the rock shaft 23,and carries a stud on which is loosely mounted a pinion 30, which is ofsufficient width to mesh with both of the gears 27 and 28, see Fig. 2. Aleather washer or disk 29 in this instance extends between the ratchetwheel 29 and the gear 28.

The ratchet wheel 29 has its hub 29 extended on one side, with anannular groove or recess therein to receive the forked end of an arm 31,which has its hub 31 fast on a rod 32, loosely mounted and slidable in ahub or boss 32 on the lower end of the stand or bracket 25. The rod 32has an engaging or ball shaped end 32".

On the rock shaft 23 is a helically coiled expansion spring 33, whichbears at one end against the hub 29 of the ratchet wheel 29, and at itsother end against the hub 34, fast on the rock shaft 23, of an arm 34,which has an arc-shaped end 34 adapted to extend under and engage a pin35 extending out from the free end of a pawl 35; the hub of said pawl 35is pivotally mounted on a stud 36, secured in a stand 37 on the frame 1.The spring 33 acts to move the ratchet wheel 29, loose on the rock shaft23, toward the left in Fig. 2, to cause the pinion 30, carried on saidratchet, to extend over the teeth of the gear 27, as shown in Fig. 2.

The rod 32 carrying the forked arm 31 is adapted to be moved by theoperator, to move the ratchet wheel 29, against the action of the spring33, to carry the pinion 30 on the ratchet wheel 29 out of engagementwith the teeth of the gear 27 fast on the cam 26, so that the cam 26 maybe more readily returned to its starting position after a set of bobbinshave been filled and a new set of empty bobbins put on the spindlesready to start.

From the above description in connection with the drawing, the operationof my improvements will be readily understood by those skilled in theart. The ring rail 4, by turning the cam 26, is moved to its lowestposition, in which position the roll 15 on the cam lever 15 will be onthe lowest part of the cam 26. The arm 34 having the curved end 34", isset on the rock shaft 23 causing the in such a position relatively tothe pawl 35, that the pawl 35 will rotate the ratchet wheel 29 as manyteeth as is required to make a bobbin of the required diameter. Forillustration, in adjusting, the rock shaft 23 may be turned, moving thetop of the ratchet 29 to the left in Fig. 1, the ex treme allowed by thecam 19 and its connections to the rock shaft 23. When this has beendone, the arm 34 may, by loosening the set screw in hub 34, be turnedtoward the left in Fig. 1, passing from beneath the pin 35 in the freeend of the pawl 35, and allowing the said pawl to engage the teeth ofthe ratchet wheel 29. The arm 34 may then be made fast to the rock shaft23, with a predetermined number of the teeth of the ratchet wheel 29between the free or operating end of the pawl 35, and the adjacentportion of the curved end 34 of the lever 34. It is obvious that whenthe shaft 23 and the ratchet wheel 29 are turned, to move the upperratchet teeth to the right, the free end of the pawl 35 will ride overthe intervening ratchet teeth between it and the adjacentsurface of theshield 34". When the pin 35 on the pawl 35 will contact with and belifted by the said surface of the shield 34", and the pawl 35 be raisedclear of the ratchet teeth and the ratchet wheel 29. When the shaft 23is again rotated in the opposite direction, carrying the upper teeth ofthe ratchet to the left, the surface of the shield 34 will pass frombeneath the pin 35 of the pawl 35, and allow said pawl to engage andhold the teeth on the ratchet wheel 29, and allowing the shaft 23 to beturned in said ratchet wheel, an amount proportional to the number ofratchet teeth over which the pawl 35 was allowed to ride during theprevious movement of the shaft 23 in the opposite direction. It will beunderstood that by causing the shaft 23 to turn within the ratchet wheel29, the same relative movement between the shaft 23 and cam 26 is causedthat would be caused by turning said ratchet wheel 29 on the shaftpinion 30 is revolved about two gears 27 and 28 meshing with the teethofboth, and .as before stated the gear 28, being fast on the shaft 23,and having one less tooth than the cam gear 27, which is loose on saidshaft, said cam gear 27 will be caused to '23, if said shaft were atrest; that is the ratchet wheel 29 is rocked with the shaft 23 in thedirection of arrow 2, Fig. 1, through the frictional engagement of thegear 27 with said ratchet wheel 29, and is also rocked in the oppositedirection by the same mechanism, until, as above explained, the end ofthe pawl 35 has passed the end of the curved end 34 on the arm 34, whensaid pawl will drop and hold the ratchet wheel 29 stationary for theremainder of the movement of the shaft 23 in that direction. The cam 26having the gear 27 fast thereon, is caused to rock with the shaft 23, bythe pinion 30 having its teeth normally in constant mesh with the teethon the same side of the center of both the gear 27 which is fast on thecam 26, and the gear 28, which is fast on said shaft 23. When throughthe operation previously explained, the pinion 30 is caused to advance atooth in mesh with the gear 28, it will also advance a tooth in meshwith the gear 27 the tooth of the gear 27 being, as previously stated,of coarser pitch, the said gear 27 being rotated on the shaft 23 a spaceequal to the difference of pitch between the teeth of the two gears 27and 28, consequently causing the cam 26 to be gradually rotated aroundthe shaft 23 at the same time it is being rocked, as above explained.This operation is repeated for each reciprocation or rocking motion ofthe shaft 23.

The gear 28, which is fast on the shaft 23, has in this instance onelesstooth than the gear 27, and therefore the revolution of the ratchetwheel 29 carrying the pinion 30 with it, causes the gear 27 to graduallyrotate the cam 26 in the same direction as the ratchet wheel 29, wherebythe cam 26 will be gradually rotated on the shaft 23, presenting aconstantly changing cam surface to the roll 15 on the cam lever 15,which is connected through rod 13, and the rocker arms with the rods 6to the ring rail 4. The cam 26 may be of any shape desired, to give abobbin the proper shape, according to the amount of up and down travelof the ring rail 4.

It will be understood that the details of construction of myimprovements may be varied if desired.
